In preliminary work, we have measured psychophysical tuning curves before and after exposing normal listeners to noise. The postexposure tuning curves are generally broader than the pre-exposure curves; further, the broadening of the postexposure tuning curves is evident for noise exposures that produce very little (less than 3 dB), or no temporary threshold shift (TTS). While recovery from TTS often proceeds linearly in log time, the broadening of postexposure tuning curves remains unchanged for an extended time. These results lead us to expect that frequency selectivity measures may be more sensitive indicators of the deleterious effects of noise exposure than TTS, and that the temporary effects of noise exposure may be more long lasting than temporary pure tone threshold shifts have indicated.
